The average American gave $5,491 to charity in 2015 According to preliminary IRS data for the 2015 tax year, the average taxpayer who claimed a charitable contribution deduction gave nearly $5,500. However, there are two things that need to be mentioned. First, this only includes the 30% of people who itemized deductions. And second, charitable contributions vary widely with income.
